To all whom it may concern..-

Be it known that we, IGNATIUS SINGER and MORITZ \Yonrr JUDELL, subjects of the Queen of Great Britain, both residing at Gresham House, Old Broad Street, in the city of London, England, have invented a new and useful Improved Apparatus for Cleansing ool and like Material, (for which we have received patents in Great Britain October 3, 1888, No. 11,217; in France, by patent of addition dated- December 8, 1888, No. 189,234; in Victoria January 11, 1889, No. 6,157; in New South Vales January 17,1889, No. 1,185; in New Zenland January 29, 1889, No. 3,511; in South Australia January 17, 1889, No. 1,212; in Queensland January 16 and July 5, 1889, No. 688; in India May 29 and June 20, 1889, No. 106; also partly patented in Austria- Hungary October 3, 1888, Nos. 18,530 and 81,611; in Belgium March 3, 1888, No. 80,861; in Canada.

Our invention relates to apparatus for cleansing wool from the oily and fatty matters, the saline matters, and the mechanical impurities which are generally associated with it, our object being to deliver the wool in it clean dry state ready for manufacture, separating from it the impurities in such form that the oil and fatty matters can be obtained as useful products, and the bisulphide of carbon which we use as the solvent can be recovered for subsequent use. \Ve will describe the apparatus which we employ for this purpose, referring to the accompanying drawings.

Figure 1 is a longitudinal section of the macerator and drying chamber connected therewith. Fig. 1 is a detail sectional View illustrating means for steam-heating certain of the rolls. Fig. 1 is a sectional view illustrating a modified construction of the partitions which divide the mncerntor into separate cells. Fig. 2 is a transverse section of the macerntor at 00 0;, Fig. 1; and Fig. 3 is a side elevation of part of the mncerator, a portion of the casing being broken away to show the interior at 00 0c.

The macerntor A is a. long vessel divided into a number of cells by vertical double partitions. At the one end B several of the cells are deeper than the others, and their double partitions are made as shown at O, that on the right reaching higher than that on the. left, but not reaching quite to the bottom of the cells. The other cells D have also double partitions E, the let t being the higher, but not reaching quite to the bottom. The partitions become lower and lower toward the left end of the macerntor. In several of the cells F, at the left hand, are arranged dredgers, which will be more particularly described hereinafter, and, finally, ut the extreme left there is a deposit-cell G. containing a filter g, above which is an outflow-pipe g, and below which is a pipe and cook g which can be opened for emptying the cell.

On the extreme right of the mncerntor is a feed-cell II, which is supplied by 2b pipe h with wnternnd bisulphide of carbon. In this cell is a flout h, adjusted so that it will float on the heavier liquid bisulphide of carbon and sink in water, so that it takes a position at the level where the two liquids meet in obedience to their relative gravities. The vertical float-rod is linked to the long arms of two lovers 7L2 7L3, the short arms of which carry valves governing the mouths of two pipes h and 7L5. \Vhen, owing to excess of hisulphide of carbon, the float it rises, it closes the valve of pipe h" and opens that of pipe 7f, allowing a portion of the bisulphide to flow to the first of the cells B. \Vhen, on the other hand, float 7L, sinks, it closes the valve of pipe 77. and opens that of pipe h", admitting water to the first of the cells B. The water overflows from cell to cell, finally escaping from the last by a pipe I). In like manner the bisulphide admitted by the pipe 7U overflows from cell to cell of the ranges D and F, finally into the deposit-cell G, and, depositing there solid matters suspended in it, passes through the removable filter g and away by the pipe g.

There are two continuous traveling aprons K and L, of wire-gauze or other porous fabric, which pass over guiderollers and travel together in the direction of the arrow between a number of pairs of pressing'rollers 7c and under idlers Z, one set for each cell, then ascenda shaft M to the drying-chamber N, in which they are similarly conducted between a number of pairs of pressing-rollers 7t" and under idlers Z, the pressing-rollers in this case being steam-heated-as, for instance, as shown in Fig. 1, where one of the rolls K is shown in section provided with suitable stuffing-boxes and ingress and egress steam pipes 76. Beyond the left end of the drying-chamber N, after passing between the pressing-rollers 70 the two aprons K L separate, to come together again at the first pair The wool in thus traveling through the macerator from left to right, while the bisulphide of carbon travels from right to left, meets purer and purer bisulphide as it advances towvard B, while the bisulphide meets wool more and more greasy as it flows toward G. In its passage along the macerator the woolis repeatedly immersed in the solvent, which is mostly pressed out by the rollers 7t after each immersion. After leaving the last of the cells D it passes in like manner through the watercells B, in which such salts as it contains that are soluble in water are washed out. The wool then passes up the shaft M and along the drying-chamber N, subject to the action of the heated rollers, and finally is delivered on the chute L in a clean dry condition, ready for manufacturing purposes.

Such being the general character and oper ation of the apparatus, there are certain de tails, which we now proceed to explain.

The shaft M and the drying-chamber N communicate with a cooling-worm O, by which the vapors are condensed, the water and the bisulphide which result from the condensation being conducted by the pipe 0 to supply again the macerator-cells. In order to pro- In order to get access to different parts of the macerator and drying-chamber, there are a number of openings through their covers, each closed by a flanged cap a, the flange of which projects down into water, forming a seal against escape of vapor. v

In several of the macerator-cells, as indicated at F, there are provided dredgers, as shown to an enlarged scale in Figs. 2 and 3, each consisting of a chain of buckets I, which pass round along the bottom of the cell, scrape up such solid matters as are deposited there in the form of sludge, and deliver it into a trough-receiver, from which it is conveyed by a worm p to an inclined chute 19, Fig. 1, leading out at the side of the macerator. For working the pressing-rollers 7c we provide a revolving shaft Q, extending along the side of the macerator within a casing g. This shaft by bevel-gear, or, it might be, by worm-gear, works the lower one of each pair of pressing rollers 70, the upper one, as well as the idler Z, being left free to be rotated by the travel of the aprons K and L. A similar arrangement of driving-gear is applied to the rollers in the drying-chamber N. The fluid that issues at g, being a solution of fatty matter in bisulphide of carbon, is dealt with by distillation, evaporating the solvent, which is condensed for subsequent use, and leaving comparatively-pure fatty matter in the still.

The sludge dredged up from the cellsF and delivered from the chute p, as well as that removed from tilne'to time from the deposittank G, is also subjected to distillation for recovery of solvent. As these are known processes, we do not describe apparatus for effecting them, there being several known forms of apparatus for that purpose.

For the purpose of emptying the macerator, each cell of it may communicate with the next by a small passage close to the bottom,

each of these passages being provided with a' valve, which can be opened, so as to form a continpous passage along the bottom of the macerator to the pipe and cock g Such a passage 6 and valve 6 are shown in Fig. 1 said valve being adapted to be moved up or down to open or close the passage by means of a handled rod 6 or a general drain-pipe (indicated by-the dotted lines 9 and g, Fig. 1) may communicate with the bottom of each cell by a branch prov ded with a cock or Valve, which can be opened to empty the cell when desired.

Having thus described the nature of our invention and the best means we know of carrying it out in practice, we claim- ITO 1.
